Mandetta predicts 2.3 million tests; fiocruz, however, projects half


In a press interview, the Minister of Health, Luiz Henrique Mandetta, confirmed the transfer of 2.3 million molecular tests for the detection of coronavirus to the states.

Despite this, the Oswaldo Cruz Foundation (Fiocruz), responsible for manufacturing, announced the production of only 30 thousand tests. It projects 50 thousand by the end of March, with the possibility of tripping to 150 thousand in April, according to the institution itself.

In addition to its own manufacturing in Bio-Manguinhos, the foundation announced the import of 1 million rapid tests from the United States. But, contrary to what Mandetta announced, the samples are serological. Therefore, they depend on a counter-test due to the low detection accuracy.

Together, the tests produced or imported by Fiocruz can reach 1.2 million_ half of what was announced by the government.

While the molecular tests, adopted until then in Brazil, take more than a day to verify the result, the serological test can come out in a few minutes.

WHO recommends more tests

Since the rapid rise of cases in the country, the government has considered limiting the performance of tests only in critical cases_ contrary to the recommendation of the World Health Organization, which guides the largest possible number of tests.

Recently, however, the Ministry of Health has promised to provide 10 million tests (serological) that will be distributed throughout the country: 5 in eight days and 5 more in the following weeks.

Rapid tests are viewed with caution

Also according to the folder, the cost of a serological test unit is R $ 75, costing the government R $ 750 million.

Serological tests, however, are considered risky due to the lack of precision in the procedures. This is because, while molecular tests analyze the virus particles, so-called rapid tests are reserved for the analysis of antibodies.

In an interview with the newspaper O Globo, infectious disease scientist Nancy Bellei, a respiratory virus researcher at the Federal University of São Paulo (Unifesp), evaluated the possibility. “This test (the serological test) is not used to exclude a health professional, for example. It serves for epidemiological surveys and for regions that do not have Covid-19 or that have very few cases). ”
